Theme for a baby boy

My daughter's theme was / is minnie so I always said if I had a son his theme would be mickey (I'm currently expecting again) and fyi not trying to sound rude but I could careless if those themes are used by many. It's just a theme , no big deal . But anyways , I now am thinking nautical theme if anyone did a nautical theme do you mind sharing pictures ? (: and any other moms , if you can share what theme you used / plan to use for your son . My husband wants his theme to be his favorite football team but i'm not a fan of his team so I don't think so 😜
